VAST Cluster Analytics provides numerous metrics for monitoring views, including Quality of Service (QoS) metrics per view.
By default, views are polled for analytics data every five minutes. You can select up to ten views at any given time for live monitoring. Views that have live monitoring enabled, are polled every ten seconds. You can see which views are currently being live monitored by checking the Live Monitor status of the view.
Live monitoring is a setting you can toggle on or off to enable and disable for each view.
Checking Live Monitoring Status
To check whether a view has live monitoring enabled or disabled:
In VAST Web UI, select Element Store -> Views to open the Views page and review the Live Monitor value for the view.
Enabling and Disabling Live Monitoring per View
To enable or disable live monitoring for a view:
In VAST Web UI:
In the left navigation menu, select Element Store and then Views.
Right-click a view and select Toggle Live Monitoring.
This option enables live monitoring, if it was disabled, or disables live monitoring, if it was enabled.
Click Yes to confirm the action.
The view now has live monitoring enabled if live monitoring was disabled previously, or disabled if it was enabled previously. The updated status is reflected in the Live Monitor column of the Views tab.
Checking View Metrics in Analytics Reports
You can generate custom or predefined analytics reports with per-view metrics.
The following predefined reports are available for views, with the ability to focus on a specific view:
Views Bandwidth

With customized analytics reports, you can select specific performance and QoS properties to show for a specific view.
